PIN DESCRIPTIONS
Symbol
Description
VDD
Power source
VSS
Circuit ground potential
AC
Pin to clear internal logic, pulled down to VSS.
After power is turned on, the MSM6352 must be reset by this pin.
TEST
Pin to test internal logic, pulled down to VSS.
This pin must be open in normal operation.
XT, XT
Input and output pins of oscillator inverter.
3.58 MHz ceramic resonator and capacitors is connedted to these pins.
HS
Input pin connected to the hook switch, pulled up to VDD.
DP OUT
Output pin of dial pulse
Dial pulse rate (10 pps or 20 pps) and Make Break ratio (40% or 33%) can be selected by
software.
DTMF OUT
Output pin of DTMF signal
BD
Output pin of buzzer sound
32 kHz
Output pin of 32 kHz clock
R1 to R4
Input port pulled down to VSS
R5 to R8
I1 to I4
Input port having clocked pull-down resistor to VSS
Only when this port is accessed, pull-down resistors are connected to this port.
C1 to C4
Output port
O1 to O4
IO1 to IO4
Tri-state bidirectional port
IOE
Output pin
When IO1-IO4 is accessed, input completion signal (when read) or load signal (when written)
is output from IOE pin.
